Description

This extension provides functionality to use a logical device that consists of multiple physical devices, as created with the VK_KHR_device_group_creation extension. A device group can allocate memory across the subdevices, bind memory from one subdevice to a resource on another subdevice, record command buffers where some work executes on an arbitrary subset of the subdevices, and potentially present a swapchain image from one or more subdevices.

Promotion to Vulkan 1.1

The following enums, types and commands are included as interactions with VK_KHR_swapchain:

If Vulkan 1.1 and VK_KHR_swapchain are supported, these are included by VK_KHR_swapchain.

The base functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum, and command names are still available as aliases of the core functionality.

Version History

  • Revision 1, 2016-10-19 (Jeff Bolz)

    • Internal revisions

  • Revision 2, 2017-05-19 (Tobias Hector)

    • Removed extended memory bind functions to VK_KHR_bind_memory2, added dependency on that extension, and device-group-specific structs for those functions.

  • Revision 3, 2017-10-06 (Ian Elliott)

    • Corrected Vulkan 1.1 interactions with the WSI extensions. All Vulkan 1.1 WSI interactions are with the VK_KHR_swapchain extension.

  • Revision 4, 2017-10-10 (Jeff Bolz)

    • Rename “SFR” bits and structure members to use the phrase “split instance bind regions”.
